Answer:
Perimeter = 32m
Area = 76.8m²
Step-by-step explanation:
Question:
On a farm they want to put an octagonal fence to keep the geese at night. They have already placed two of the sides and used 8 meters of fence. If we know that the apothem is 4.8 meters, what will be its perimeter? And your area?
Octagonal polygon is a polygon with 8sides.
Two sides of fence = 8m
One side of fence = 8/2 = 4m
Each sides = 4m
Apothem = 4.8m
Let's look at the steps that will enable us solve this question.
The area of a regular polygon is calculated as:
Area = ½ap
where a = the apothem of the polygon
p= the perimeter of the polygon.
Apothem is the distance between the centre of the polygon and the base of the polygon.
The perimeter (p) = The sum of all sides of the octagon
p = (4 + 4 + 4 + 4 + 4 + 4+ 4+ 4 )
p = 4(8)
perimeter (p) = 32m
Area = ½ ×a ×p = ½ × 4.8m × 32
Area = 153.6/2
Area = 76.8m²
Let
x---------> the original amount
we know that
<span>a percent increase of 12% of x is
x*[100%+12%]/100------> x*[112]/100----> x*1.12
</span>1.016x
x*[100%+1.6%]/100------> x*[101.6%]/100---> 1.016x
so
1.016x-------> represent a percent increase of 1.6% of x
so
the answer is
1.016x is not a percent increase greater than 12%
